2000 Toyota Solara Q&A
2000 Toyota Solara Question: There is a humming noise thats coming from under the car at 2100rpm idle.
Took it to Autozone to check it, they said its in the evap system, something could be clogged or fuel cap. Took to a mechanic, 2nd time he cleared it @ it never comes back on, now. But I told him before he cleared the light, I smelled "gas in the oil" when checking the oil. Im surely thinking he's bypassed something in the circuit to make the light NOT come back on, cause he viewed me as a pest, though I asked him to fix it.?? Few wks later, In any case Now the car whines off and on somtimes kinda loud just from underneath,as it resonates and you cant pinpoint it.. Till the other day when I took it to a muffler shop that put it on the lift and found a egr thing located under @ by the gas tank. He jiggled it @ it quit making the sound. Thinking a solenoid may had been stuck..? Though it,the noise, came back 2 days later, "today." Any Advice or similar happenings that I might can do to FIX Myself. It shifts out fine.. And it has 203,870 miles. Has New plugs,timing belt, belts, fuel filter, radiator fluid changed, and hoses too.. just saying. Excellent condition. - bigpaul
I suspect a valve or solenoid on the charcoal canister for the evaporative emission system is having a problem. You had mentioned the possibility that it may be an EGR related problem but the EGR valve and solenoid switching valve are in the engine compartment. It would be important to note the trouble cods stored but the evap canisters do give problems. - patrick mannion
